Have a look at this previous discussion.

But, i did not find solution of my question from your previous discussion

there no solution of Active Screen Capturing in Java , i think.

How did you change your code after reading that thread? Are you passing the rectangle of the frontmost window to the createScreenCapture method?

I tried to pass 'new Rectangle(this.getScreenSize)' but failed to compile.
Can you tell me , what should i pass to createScreenCapture for most front window?

waiting ... .

If that screen is part of your own application it's quite easy. However, it probably isn't, so I doubt there is anything you can do without using JNI, because you'll need to use the Windows / Xorg / XFree API.

You forgot the parentheses after getScreenSize. Also note that the method is part of the Toolkit class, so unless "this" is a Toolkit implementation -and I'm certain that it is not- it won't work the way you currently have it. The other discussion actually lists the code required - why don't you just copy and paste it?
